Abstract

Erfindungsgemäß wird von einer Empfangsstation ein aus Datensymbolen bestehendes Empfangssignal empfangen. Das Empfangssignal wird empfangsseitig in einzelne Abtastwerte zerlegt und zur Bestimmung von Kanalkoeffizienten mit bekannten Datensymbolen verglichen, wobei in der Empfangsstation einzelne bekannte Datensymbole des Empfangssignals gespeichert sind. Dadurch, daß für sich schnell bewegende Mobilstationen eine reduzierte Anzahl von Kanalkoeffizienten bestimmt wird, verbessert sich für diese Kanalkoeffizienten die Schätzgenauigkeit.
